Saudi Skyscraper Architect Grapples With Wind at 3,000 Feet

Kingdom Tower, Saudi Prince Alwaleed bin Talal’s project to erect the world’s tallest building in Jeddah, is designed to imitate the contours of a sprouting desert plant. Adrian Smith’s task is to make sure it doesn’t sway in the wind like one.

The American architect has the right resume for the job. He already grappled with effects like horizontal wind divergence and negative pressure high above the Persian Gulf desert when he designed Dubai’s Burj Khalifa, today’s highest tower.
